碳化硼

Boron carbide is produced by smelting boric acid and carbon powder in an electric furnace at high temperature. The theoretical density is 2.52 g / cm, the melting point is 2450 ° C, and the micro hardness is 4950 kg / cm. Its extremely high hardness is second only to diamond and cubic boron nitride. Due to its high temperature resistance, acid and alkali corrosion resistance, high strength, high chemical stability, high elastic modulus, and low specific gravity, it has become an ideal material for many industries.
